Firefly Aerospace currently plans for its maiden Alpha rocket launch to happen as early as Dec. 22, co-founder and CEO Tom Markusic told CNBC, as his company prepares for the next major milestone in its plan to offer a variety of space transportation services.

Markusic is confident in the launch date because of the “rigid” requirements of Vandenberg Air Force Base in California, where Firefly is finishing up work to prepare the launchpad at SLC-2. While “everything is susceptible to surprises,” with room in the schedule to launch as late as Jan. 31, Markusic said the “full gamut of rules” at Vandenberg means the company has put extra work into certification for Alpha’s first launch.

“We took the hard route to flight, and that was by going to a launch range that has very strict requirements,” Markusic said. “So our design has been highly vetted, as we have a lot of requirements that are put on us by the range and that makes the rocket ultimately more reliable.

“The mobile gravity suit is a small, untethered, and flexible intravehicular activity (IVA) suit,” the researchers wrote in their paper published in the Frontiers in Physiology journal.

The idea is to give astronauts maximum flexibility while on board a spacecraft, without reducing crew time. “With the gravity suit, astronauts will be able to float freely around the space station while adhering to their every day tasks,” the paper reads.

“The negative pressure is generated by its own portable vacuum system, ensuring full mobility, and user-control,” the paper reads.

Suddenly, a billion miles doesn’t seem so far.

Experts say the right kind of propulsion system could carry spacecraft to Saturn in just two years. The direct fusion drive (DFD), a concept being developed by Princeton Plasma Physics Laboratory, would make extremely fast work of the nearly billion miles between Earth and Saturn.

ALBUQUERQUE, N.M. — The president of Virgin Galactic gave state lawmakers an update Monday on the company’s progress toward commercial spaceflight.

Virgin Galactic President Mike Moses said the first test space flight from Spaceport America will happen sometime this fall, which is the final step before taking paying customers into space.

Let’s get this over with once and for all: We are going to Mars. The only questions are: When? Who? How? Which way? And, of course, why?

Why?

Science and civilization.
