Astra
Astra Space, Inc. is an American aerospace company that develops small-lift launch vehicles and spacecraft engines aimed at enabling frequent, low-cost access to orbit for small satellites and payloads. Founded in 2016 by Chris Kemp, a former NASA Chief Technology Officer who also co-founded the OpenStack cloud computing project, and Adam London, the company is headquartered in Alameda, California, and initially focused on rapid iteration of its Rocket 3 expendable rocket to achieve high launch cadence.[1][2] Astra gained attention for its first successful orbital launch in November 2021, when its Rocket 3.2 vehicle reached low Earth orbit roughly five years after inception, positioning it among the quickest privately funded entities to demonstrate such capability; a follow-up mission in March 2022 deployed 22 customer satellites.[3][4] However, the program was plagued by reliability issues, with only two full successes amid eight failures, including a June 2022 mishap caused by a second-stage cooling malfunction that destroyed four NASA cubesats intended for hurricane research.[5][6] The company went public in 2021 via a SPAC merger valued at $2.1 billion but saw its market capitalization plummet over 99% by 2023 due to unmet promises of monthly launches and an overestimated addressable market, prompting investor class-action lawsuits alleging misleading disclosures on operational readiness and revenue potential.[7][8] In 2024, Kemp and London took Astra private for approximately $30 million, delisting it from Nasdaq amid cash shortages and workforce reductions, before securing $80 million in new funding and a U.S. Defense Innovation Unit contract worth up to $44 million to advance Rocket 4, a next-generation vehicle targeting mid-2026 debut for potential military resupply and global point-to-point cargo delivery.[9][10][11]Etymology
Linguistic origins and general usage
The Sanskrit term astra (अस्त्र) derives from a verbal root connoting "to throw" or "to project," reflecting its primary denotation as a thrown or missile-like weapon in ancient texts.[12] This etymological foundation distinguishes it from shastra, which refers to hand-held or contact weapons, as astra emphasizes projection or launch, such as arrows, darts, or spears.[13] In classical Sanskrit lexicography, astra is defined as a neuter noun encompassing missiles, arrows, or even bows in some contexts, underscoring its association with ranged armament.[14] In Vedic and epic literature, astra generally denotes any implement designed for throwing or propulsion, often invoked through ritualistic recitation to enhance efficacy, though this usage predates specialized mythological attributions.[15] The term appears across grammatical traditions, including Panini's Ashtadhyayi, where it functions as a standard vocabulary item for weaponry without inherent supernatural connotation in baseline linguistic application.[15] Distinctions from shastra are explicit in texts like the Ramayana, where astra equates to missiles separable from the wielder, contrasting with retained blades or clubs.[13] Beyond Sanskrit, astra has limited direct cognates in other Indo-European languages, though its conceptual focus on projection parallels roots for "throw" in Proto-Indo-European reconstructions like yewǵ-. In modern English and Indological scholarship, the word is transliterated to describe classical Indian weaponry, retaining its projectile essence while avoiding conflation with contemporary armaments.[16] Usage remains precise to philological contexts, eschewing broader metaphorical extensions seen in unrelated Latin astra ("stars").[17]Mythology and religion
Astras in Hindu epics
In the Hindu epics Ramayana and Mahabharata, astras denote transcendental weapons invoked through precise mantras, distinct from mundane shastras, and governed by specific deities that imbue them with elemental or cosmic powers. These armaments materialize upon utterance of their associated incantations, enabling effects ranging from targeted incineration to illusory submersion or serpentine immobilization, often scaling to affect entire armies if uncontrolled. Warriors acquired astras via rigorous tapasya, divine boons, or guru-shishya transmission, as exemplified by Arjuna's penance for the Pashupatastra from Shiva or Rama's inheritance from Vishwamitra. Their deployment highlights themes of dharma-bound restraint, as misuse risked apocalyptic fallout, such as ecosystem devastation or perpetual enmity between discharged weapons.[18][19] Key astras feature prominently in epic battles, underscoring strategic and spiritual warfare. In the Ramayana, Indrajit deploys the Brahmastra against Lakshmana, countered only by Hanuman's intervention, while Rama employs the Vaishnava Astra to neutralize Ravana's defenses. The Mahabharata's Kurukshetra conflict escalates with astras like the Narayanastra, unleashed by Ashwatthama to raze Pandava forces indiscriminately, requiring total surrender for mitigation. Such weapons' invocation demanded purity of intent; ethical lapses, as with Ashwatthama's vengeful Brahmashirastra targeting the Pandava lineage, invited curses or self-inflicted harm, reflecting causal consequences of adharma.[18][20] The following table enumerates principal astras attested in the epics, drawn from textual descriptions of their invocation and deployment:| Astra | Presiding Deity | Primary Effect | Notable Epic Usage |
|---|---|---|---|
| Brahmastra | Brahma | Generates intense firestorm annihilating targets, potentially worlds if unwithdrawn | Rama against Ravana (Ramayana); Ashwatthama against Pandavas (Mahabharata) |
| Pashupatastra | Shiva | Unleashes uncontrollable destruction mimicking Shiva's tandava, incinerating all | Granted to Arjuna but unused in Kurukshetra; symbolic of ultimate restraint |
| Narayanastra | Vishnu/Narayana | Multiplies into homing discs slaying resistors; neutralized by prostration | Ashwatthama vs. Pandava army, sparing submitters (Mahabharata) |
| Agneyastra | Agni | Summons flames consuming organic matter instantaneously | Arjuna and Karna in duels; Indrajit against vanara forces (Ramayana) |
| Varunastra | Varuna | Induces drowning illusion or torrential floods immobilizing foes | Bhishma against Abhimanyu; Lakshmana defensively (Ramayana) |
| Aindrastra | Indra | Hurls thunderbolts or dart showers piercing armor | Frequent in Kurukshetra by multiple warriors; Rama vs. marine demons |
| Nagastra | Nagas | Conjures binding serpents paralyzing and poisoning targets | Karna vs. Arjuna; countered by Garudastra (Mahabharata) |

Automobiles
The Opel Astra is a compact car (C-segment) manufactured by the German automaker Opel since September 1991, succeeding the long-running Kadett model after 85 years of compact-class production. Offered primarily as a five-door hatchback but also in sedan, wagon, coupe, and convertible variants across generations, it has emphasized practicality, fuel efficiency, and progressive design updates. In the United Kingdom and select markets, it is marketed as the Vauxhall Astra, with production adapted for right-hand drive. By 2024, the Astra reached its sixth generation (Astra L), incorporating hybrid and fully electric powertrains amid electrification trends.[69] The first generation, Astra F (1991–1998), debuted with front-wheel drive, inline-four engines ranging from 1.4-liter petrol (60 hp) to 2.0-liter (150 hp), and options for manual or automatic transmissions; it achieved strong sales with 4.13 million units produced, bolstered by features like optional anti-lock brakes and improved rust protection over the Kadett. Subsequent generations evolved: Astra G (1998–2004) introduced a sleeker "space frame" design and diesel common-rail engines for better efficiency; Astra H (2004–2010) added adaptive chassis control (IDS) and a twin-top convertible; Astra J (2009–2015) featured a "blade" taillight signature and front-wheel-drive-only layout with turbocharged options up to 180 hp; Astra K (2015–2021) adopted lightweight high-strength steel for reduced weight (by up to 200 kg) and integrated infotainment; while the current Astra L (2021–present), built on the Stellantis EMP2 platform, offers plug-in hybrid variants delivering 180 hp with up to 37 miles of electric range and a pure electric model with a 156 hp motor and 257-mile WLTP range.[70][69][71] Production occurs at Opel's Rüsselsheim and Gliwice facilities, with annual European sales fluctuating but remaining competitive in the family hatchback segment; for instance, early 2000s figures exceeded 200,000 units yearly before market shifts toward SUVs impacted volumes. The model has garnered praise for handling dynamics and value, though critics note average interior quality in mid-generations compared to rivals like the Volkswagen Golf. A short-lived North American variant, the Saturn Astra (2008–2009), sold under 7,000 units due to reliability issues and recession timing.[72][73]Aviation
The IAI Astra is a family of twin-engine business jets developed by Israel Aerospace Industries (IAI), derived from the earlier Westwind series but featuring a new forward fuselage, wings, and landing gear while retaining the tail and engine nacelles. The initial Astra 1124 model achieved its first flight on March 21, 1984, and entered service in 1985 as a medium-range corporate aircraft capable of carrying up to eight passengers.[74][75] Powered by two Honeywell TFE731-3C turbofan engines each producing 3,700 lbf of thrust, it offered improved performance over predecessors with a maximum speed of approximately 480 knots and a range exceeding 2,800 nautical miles with four passengers.[76] Subsequent variants enhanced efficiency and range. The Astra SP, introduced in the early 1990s, incorporated aerodynamic refinements and upgraded avionics for better high-speed cruise capabilities. The Astra SPX, certified in 1996, featured more powerful Honeywell TFE731-40R engines rated at 4,250 lbf each, enabling a maximum operating altitude of 45,000 feet, a cruise speed of 465 knots, and a seats-full range of 2,456 nautical miles.[77][78] Its dimensions include a length of 55 feet 7 inches, wingspan of 52 feet 8 inches, and a cabin measuring 17.1 feet long by 4.9 feet wide, accommodating up to nine passengers with a full-width aft lavatory and forward galley.[77][79] In 2001, IAI sold the program to Gulfstream Aerospace, which rebranded the SPX as the Gulfstream G100 and continued production until 2005, with approximately 200 units of the Astra series built overall. The aircraft's supercritical wing design and advanced flight controls contributed to its reputation for fuel efficiency and short-field performance, making it suitable for transcontinental operations. Operating costs averaged around $1,983,333 for acquisition in the secondary market as of recent listings, with emphasis on its balance of speed, range, and economy in the midsize jet category.[80][81]Rail transport

The company traces its origins to 1882 and has manufactured over one million freight wagons, positioning it as a major European producer with an annual capacity exceeding 5,000 units.[82][83] In June 2017, Astra Rail merged with Greenbrier Europe in a transaction valued at approximately €60 million, creating Greenbrier-Astra Rail, which became Europe's largest integrated freight railcar manufacturing, engineering, and maintenance entity serving markets in Europe, Eurasia, and Africa.[84][85] The combined operations emphasized compliance with international standards, including recent developments like the first fully STI-compliant railcar showcased in October 2025 at Railway Days, highlighting Romanian production at European quality levels.[86] Astra Vagoane Călători, affiliated with the Astra group in Arad, focuses on passenger rolling stock, including international traffic cars, subway vehicles, trams, and components like bogies and casings, with full in-house testing capabilities.[87] Astra Trans Carpatic, another entity within the broader Astra rail ecosystem, operates passenger services in Romania, including sleeper trains and regional routes; in April 2024, it received its first electric multiple unit (SFEMU EU01) from Chinese manufacturer CRRC, transported via the port of Constanța for deployment on electrified lines.[88] In April 2025, Greenbrier announced the closure of the Arad facility, citing operational efficiencies, though the company reported €241 million in revenue for 2023 with nearly 2,300 employees and plans to sustain production in Caracal and Drobeta-Turnu Severin.[85]Spaceflight vehicles and services
Astra Space, an American aerospace company founded in 2016, specializes in small-lift launch vehicles designed for rapid deployment of small satellites into low Earth orbit, targeting payloads up to 150 kilograms. The company's initial focus was on the Rocket 3 family, a two-stage, liquid-fueled rocket powered by Delphin engines using RP-1 and liquid oxygen, with a height of approximately 11.6 meters and capability for sun-synchronous orbits.[89][90] Early development included suborbital test flights: the first on July 20, 2018, which failed shortly after liftoff due to engine issues, followed by a second on November 29, 2018, that also ended in failure from structural problems during ascent. Orbital qualification attempts began in 2020, with launches from Kodiak, Alaska, experiencing engine-out events and trajectory shortfalls, resulting in no successful orbital insertions until November 20, 2021. On that date, Rocket 3.3 (LV0007) achieved orbit during the US Space Force's STP-S26 mission, marking Astra's first orbital success despite subsequent payload deployment challenges.[90][91] Subsequent Rocket 3 flights in 2022 faced further setbacks, including a January launch abort and engine failures leading to the vehicle's retirement by mid-2022 amid operational and financial difficulties. In response, Astra shifted development to Rocket 4 (also known as Launch System 2), a redesigned medium-lift vehicle with enhanced payload capacity targeting 300-500 kilograms to low Earth orbit, incorporating modular ground systems for faster turnaround and improved reliability through relocated critical components. As of October 2025, Rocket 4 remains in development, with a first flight targeted for mid-2026 from sites including Cape Canaveral, Florida, following a $11.5 million US Space Force contract awarded in 2023 for the STP-S29B mission originally slated for 2025 but delayed.[92][11][93] Beyond launch vehicles, Astra provides ancillary spaceflight services, including spacecraft engines such as the flight-proven Astra Spacecraft Engine, an electric propulsion system for satellite station-keeping and orbit raising, integrated into third-party missions like SpaceX's Transporter-13 in October 2025. Launch services emphasize flexibility from US spaceports like Alaska's Pacific Spaceport Complex and Florida's Space Launch Complex 36, supporting a range of inclinations for commercial and government small satellite operators, though historical reliability issues have limited contracted flights to primarily demonstration and experimental payloads.[94][95]Military and weaponry
