What was the ESA Rosetta mission and what did it accomplish in November 2014?

Rosetta orbited Comet 67P for over a year and deployed the Philae lander, achieving the first landing on a comet Rosetta intercepted a comet entering the inner solar system and redirected it with a kinetic impactor Rosetta flew through the tail of Comet Halley and collected samples using an aerogel collector Rosetta flew alongside a comet for a decade without entering orbit, taking photographs from a distance

What is ESA's Gaia mission doing?

Studying dark energy by observing distant supernovae in galaxies far beyond the Milky Way Mapping the precise positions, distances, and motions of about one billion stars in the Milky Way with unprecedented accuracy Measuring the cosmic microwave background radiation left over from the Big Bang Searching for gravitational waves from merging neutron stars using laser interferometry

What did India's Chandrayaan-1 mission discover in 2008?

An ancient magnetic field that once protected the Moon from solar wind Water molecules on the surface of the Moon, including in the polar regions Evidence of a past lunar ocean in the Mare Imbrium basin The presence of helium-3, a rare fusion fuel, in the lunar regolith

What historic achievement did India's Chandrayaan-3 mission accomplish in August 2023?

It orbited the Moon and discovered a new permanently shadowed crater containing vast water ice reserves It made the first successful soft landing at the lunar south polar region, making India the fourth country to land on the Moon It landed on the Moon's far side for the first time without needing a relay satellite It successfully returned lunar soil samples to Earth on its very first Moon landing attempt

What made India's Mars Orbiter Mission (Mangalyaan) particularly remarkable in 2013-2014?

It was the first spacecraft to land on Mars and survive for more than one month India reached Mars orbit on its very first attempt and at a fraction of typical mission costs, making ISRO only the fourth agency to reach Mars It discovered methane in Mars's atmosphere at levels ten times higher than previously measured It was the first Mars mission jointly operated by two different countries

What did Japan's Hayabusa 2 mission accomplish?

It flew past Jupiter and its four large Galilean moons, sending back close-up images It collected samples from asteroid Ryugu and returned them to Earth in 2020 — including pristine carbonaceous material from the early solar system It landed on the Moon's far side and confirmed the presence of water ice at the south pole It intercepted a comet and returned samples from its nucleus to Earth for the first time

What did China's Chang'e 4 mission achieve in January 2019?

The first crewed Chinese landing on the Moon's near side near the Apollo 11 landing site The first ever soft landing on the far side of the Moon, requiring a relay satellite in lunar orbit for communications The first spacecraft to land on the Moon's south pole and drill for water ice The first mission to place a space telescope in lunar orbit to observe the universe

What did China's Chang'e 5 mission accomplish in 2020?

It deployed a rover that found evidence of ancient flowing water in a lunar valley It collected and returned 1.7 kg of Moon rocks to Earth — the first lunar sample return since the Soviet Luna 24 mission in 1976 It successfully landed two astronauts on the Moon during China's crewed lunar program It placed China's first permanent lunar base module on the surface

What is China's Tiangong space station, and what does it represent?

A Chinese robotic observatory in lunar orbit studying the Moon's interior A Chinese module that was added to the ISS to expand its capacity China's own permanently crewed modular space station, representing China's rise as a major independent space power A Chinese cargo spacecraft that resupplies the ISS every six months

Which of the following best describes the current global state of space exploration?

Only the US and Russia can currently launch humans to space, while other nations can only launch satellites Space exploration has expanded beyond the US and Russia to include Europe, India, Japan, China, and commercial companies, making it a truly global endeavor The ISS has brought all major space nations together into one single cooperative program Most current space missions are funded by private companies rather than government agencies
