In late March, I traveled to Puerto Rico to conduct observations of Venus using the Arecibo Observatory telescope. It was the second time I traveled to the observatory to make radar measurements of the surface of Venus. Even though it was my second time there, the size and capability of the telescope still impressed me; the telescope is largest single-aperture telescope ever constructed.
Of the four known giant planets in our solar system, Jupiter is by far the largest. It is wider than 11 Earths side by side and has more mass than all the other seven planets combined. It is made up mostly of hydrogen and helium and has strong winds and storms.
On April 7, 2017, New Horizons entered a 157-day-long hibernation. New Horizons is an interplanetary space probe and is NASA’s first mission to Pluto and the Kuiper Belt. After operating steadily for almost two and a half years, the spacecraft and its systems deserve this much-needed break.
The Cassini spacecraft has spent almost 13 years exploring the beautiful giant planet Saturn and its amazingly diverse moons. Cassini’s mission will end in September when it plunges into Saturn’s atmosphere, but it will leave behind a wealth of knowledge and wonder.
Dr. Tom Barclay is a senior research scientist at NASA Ames Research Center. He spends his days studying stars and planets and how they formed. But before he became a scientist, he had all kinds of jobs from cleaning toilets to washing pots. He’s got some great advice about finding your own path.
SpaceShipOne signaled the beginning of a new age of spaceflight. The privately built and piloted craft reached space and returned safely to Earth in 2004. The successful flight marked a major milestone toward the future of commercial spaceflight. Despite the success of SpaceShipOne and other private ventures, spaceflight continues to be a logistical and monetary challenge.
If given the opportunity, would you travel into space?
Mariner 10 may have been the last of the Mariner spacecraft series, but it was the first to complete many new tasks. It was the first U.S. spacecraft to visit two planets - Venus and Mercury - in one mission. It was also the first to broadcast images of Venus back to Earth. The greatest achievement of the spacecraft was its use of a gravitational assist: Mariner 10 used Venus’ gravitational field to slingshot itself towards Mercury, saving fuel and picking up speed.
Hunting for exoplanets is an exciting field as more and more worlds are discovered. Many of these newly discovered planets are in the "Goldilocks Zone" where conditions may be right to support life. Dr. Hannah Wakeford is on the cutting edge of this research.
A human mission to Mars will take anywhere from two and a half to three years. That is NASA’s best estimate, with each leg of the trip taking six months and including an 18 to 20 month stay on the Red Planet. That does not sound like an extremely long-term prospect until one considers the fact that the world record for the longest single stay in Earth orbit belongs to Soviet cosmonaut and physician Valeri Poliakov at 437 days and 18 hours aboard the Mir space station in 1994-1995. That is less than half the time it would take to complete a mission to Mars.
