Space – Fill in the Blank – GK Questions

Vikram landed at approximately 69°S latitude near the lunar south pole, a region of significant scientific interest due to permanently shadowed craters potentially containing water ice.

GSAT-24 was built by ISRO and transferred to NewSpace India Limited (NSIL), which leased full capacity to Tata Play for direct-to-home broadcasting.

STS-31 aboard Space Shuttle Discovery deployed Hubble on April 24, 1990. Subsequent servicing missions corrected its optics and upgraded instruments.

PRL was established in 1947 in Ahmedabad and serves as a premier research institute for space sciences, supported by ISRO and DST.

L1 is a gravitational equilibrium point between the Sun and Earth, approximately 1.5 million km from Earth toward the Sun, allowing continuous solar observation.

Space Shuttle Challenger broke apart 73 seconds after liftoff on January 28, 1986, killing all seven crew members. The cause was O-ring failure in cold weather.

HSFC was established in Bengaluru in 2019 to coordinate all aspects of India's human spaceflight programme, including astronaut training and mission management.

Chandra is a flagship NASA space telescope launched in 1999, dedicated to X-ray astronomy, observing high-energy phenomena like black holes and supernova remnants.

ISRO renamed its earth observation satellites from IRS (Indian Remote Sensing) to EOS (Earth Observation Satellite) starting with EOS-01 in 2020 to better reflect mission purpose.

The RLV-TD LEX (Landing Experiment) successfully demonstrated autonomous landing on a runway at Aeronautical Test Range, Chitradurga, in April 2023.

Artemis is NASA's lunar exploration program, with international partners, aiming to land the first woman and next man on the Moon's south pole region.

Aditya-L1 carries seven payloads: four for remote sensing (e.g., VELC, SUIT) and three for in-situ measurements (e.g., ASPEX, PAPA), studying the photosphere, chromosphere, corona, and solar wind.

SAC is located in Ahmedabad, Gujarat. It designs and develops payloads for communication, navigation, and remote sensing satellites.

After an oxygen tank exploded en route to the Moon in 1970, astronaut Jack Swigert reported, 'Houston, we've had a problem here.' The crew safely returned to Earth despite the crisis.

ISRO's Semi-Cryogenic Engine uses refined kerosene (RP-1) as fuel and LOX as oxidizer. It offers higher thrust and density compared to cryogenic engines, intended for future heavy-lift vehicles like NGLV.

LVM3-C25 (formerly GSLV Mk III-D1) was the first successful developmental flight in 2017, launching the GSAT-19 satellite. It later launched Chandrayaan-2 and Chandrayaan-3.

NRSC is located in Hyderabad. It is responsible for remote sensing satellite data acquisition, processing, and dissemination.

JWST is optimized for infrared astronomy, allowing it to peer through dust clouds and observe the earliest galaxies formed after the Big Bang.

Salyut 1 was the first space station launched into low Earth orbit by the Soviet Union on April 19, 1971.

LPSC has a major facility in Mahendragiri, Tamil Nadu, where liquid and cryogenic stages are tested and integrated.
