Just a little over two years since Felix Baumgartner broke USAF Colonel Joseph Kittinger’s stratospheric jump record, Alan Eustace from Google has independently smashed the high altitude skydiving record again. This brings home to Silicon Valley a record that might stand for a while. Eustace took a minimalist approach to the jump. His setup involved a helium filled balloon and just him hanging from the balloon in a spacesuit. Pure and simple, this permitted his system to reach 135,890 feet above the Earth, over 41 kilometers altitude, exceeding Baumgartner’s record by 7000 feet.
The simple design of his balloon launch might remind one of a bungy jump. This one maxed out at 822 mph and created a sonic boom. How can anyone break his record now? Can someone rise to a higher altitude? What is next for the Google high flyers? Will Baumgartner take this as a challenge to retake the record?
Will cubesats lead to a new technological branch of astronomy? Goddard engineers are taking the necessary steps to make cubesat-sized telescopes a reality. (Credit: NASA, UniverseToday/TRR)
One doesn’t take two cubesats and rub them together to make static electricity. Rather, you send them on a brief space voyage to low-earth orbit (LEO) and space them apart some distance and voilà, you have a telescope. That is the plan of NASA’s Goddard Space Flight Center engineers and also what has been imagined by several others.
Cubesats are one of the big crazes in the new space industry. But nearly all that have flown to-date are simple rudderless cubes taking photos when they are oriented correctly. The GSFC engineers are planning to give two cubes substantial control of their positions relative to each other and to the Universe surrounding them. With one holding a telescope and the other a disk to blot out the bright sun, their cubesat telescope will do what not even the Hubble Space Telescope is capable of and for far less money.
The first photo of Earth from space was taken on Oct. 24, 1946 (Credit: White Sands Missile Range/Applied Physics Laboratory)
These days we see photos of our planet taken from space literally every day. Astronauts living aboard the International Space Station, weather and Earth-observing satellites in various orbits, even distant spacecraft exploring other planets in our Solar System… all have captured images of Earth from both near and far. But there was a time not that long ago when there were no pictures of Earth from space, when a view of our planet against the blackness of the cosmos was limited to the imagination of dreamers and artists and there was nothing but the Moon orbiting our world.
On this day in 1946, before Apollo, before Mercury, even before Sputnik, that was no longer the case.

As Comet Siding Spring passed close by Mars on Sunday (Oct. 19), NASA’s newest Mars spacecraft took a time-out from its commissioning to grab some ultraviolet pictures of its coma. What you see above is hydrogen, a whole lot of it, leaving the comet in this picture taken from 5.3 million miles (8.5 million kilometers).
The hydrogen is a product of the water ice on the comet that the Sun is slowly melting and breaking apart into hydrogen and oxygen molecules. Because hydrogen scatters ultraviolet light from the Sun, it shows up rather clearly in this picture taken by the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.
