With reference to the Nancy Grace Roman Space Telescope, consider the following statements: 1. It features a wide-field instrument with a field of view 100 times larger than that of the Hubble Space Telescope. 2. Its primary scientific objectives include investigating dark energy and conducting an exoplanet microlensing census. 3. It operates in a low Earth orbit at an altitude of approximately 400 km, matching the International Space Station. Which of the statements given above are correct?

Consider the following statements regarding ISRO's EOS-05 satellite launched on GSLV-F17 in September 2026: 1. It is India's first Earth-observation satellite positioned in geostationary orbit (GEO). 2. Unlike low Earth orbit satellites that pass over a region periodically, a geostationary satellite remains stationary relative to the Earth's surface. 3. The satellite was launched using India's Small Satellite Launch Vehicle (SSLV) from Thumba. Which of the statements given above are correct?

With reference to the architecture and capability of SpaceX's Starship system, consider the following statements: 1. It is designed to be fully reusable, comprising the Super Heavy first stage booster and the Starship spacecraft. 2. It has been selected by NASA as the Human Landing System (HLS) for the Artemis III and IV crewed lunar missions. 3. Starship uses solid chemical propellant motors that cannot be throttled or relit in space. Which of the statements given above are correct?

Consider the following statements regarding the concept of Space-Based Solar Power (SBSP) and Orbital Data Centers (e.g. Project Suncatcher): 1. Orbital computing leverages constant unfiltered solar energy availability in sun-synchronous or geostationary orbits. 2. Spacecraft radiate heat into the vacuum of space exclusively through convective atmospheric air currents. 3. Operating AI accelerators in space avoids terrestrial land use, freshwater cooling demands, and regional electric grid constraints. Which of the statements given above are correct?

With reference to low Earth orbit (LEO) satellite mega-constellations (such as Starlink and Project Kuiper), consider the following statements: 1. LEO satellites operate at altitudes between 500 km and 1,200 km, offering lower transmission latency compared to geostationary satellites. 2. LEO satellites remain permanently stationary over a single fixed geographical location on Earth. 3. The proliferation of mega-constellations increases the risk of orbital collisions and light pollution affecting ground-based optical astronomy. Which of the statements given above are correct?

Consider the following statements regarding the technological significance of ISRO's SpaDeX mission: 1. It validates autonomous rendezvous and docking sensors between two satellites in orbit. 2. In-space docking is a prerequisite capability for constructing multi-module orbital space stations. 3. Successful docking technology enables robotic satellite refueling and active orbital debris removal missions. Which of the statements given above are correct?
