"Suborbital" is a term you'll be hearing a lot as Sir Richard Branson flies aboard Virgin Galactic's VSS Unity winged spaceship and Jeff Bezos flies aboard Blue Origin's New Shepard vehicle to touch the boundary of space and experience a few minutes of weightlessness.
But what exactly is "suborbital?" Simply put, it means that while these vehicles will cross the ill-defined boundary of space, they will not be going fast enough to stay in space once they get there.
If a spacecraft—or anything else, for that matter—reaches a speed of 17,500 mph (28,000 km/h) or more, instead of falling back to the ground, it will continuously fall around the Earth. That continuous falling is what it means to be in orbit and is how satellites and the Moon stay above Earth.
Party time: Champagne and celebrities mark Branson's space flight

Champagne flowed, guests cheered and Grammy-nominated singer Khalid debuted a new single: British billionaire Richard Branson threw himself a party in the desert to mark his successful first flight into space.
The eccentric septuagenarian founder of Virgin Galactic arrived before dawn at Spaceport America, built in large part at his initiative, in the US state of New Mexico.
The sun rose on the building's futuristic glass facade, located in a region that boasts 340 days of good weather per year.
A small crowd of invited guests, baking under the hot sun, cheered as the space crew climbed into a black SUV and headed for the rocket, which sat at the end of a 3.6 kilometer (2.2 miles) track.

DARPA successfully deployed two satellites on June 30 as part of the SpaceX Transporter 2 launch. Both Mandrake 2 spacecraft, Able and Baker, are functioning well and progressing through checkout and commissioning.
Conceived as an early risk-reduction flight for DARPA's Blackjack program, the Mandrake 2 mission will prove out advanced laser communications technologies for a broad governmen Moscow not excluding dialogue with US on Russia's latest weapons systems

Moscow is not ruling out a dialogue with the United States on Russia's latest weapons systems if it also includes talks on American prospective hypersonic weapons and other issues, Deputy Foreign Minister Sergey Ryabkov said.
"I do not know, but I think that you can't do it without talking about them [Russian weapons systems]. But equally, Americans must proceed from the fact that we will OSU drone expertise is supporting the exploration of Earth and the Final Frontier

As a descendent of pioneers who crossed the Plains 150 years ago to establish a new life in what was then referred to as The Oklahoma Territory, it's ironic that the work that I and others in the State of Oklahoma are doing today related to Unmanned Aerial Systems (UAS) has placed the State back at the center of what can best be described as the new "wild west of aviation."

Swashbuckling entrepreneur Richard Branson hurtled into space aboard his own winged rocket ship Sunday in his boldest adventure yet, beating out fellow billionaire Jeff Bezos.
The nearly 71-year-old Branson and five crewmates from his Virgin Galactic space tourism company reached an altitude of about 53 miles (88 kilometers) over the New Mexico desert—enough to experience three to four minutes of weightlessness and see the curvature of the Earth—and then safely glided home to a runway landing.

Scientists solve 40-year mystery over Jupiter's X-ray aurora

A research team co-led by UCL (University College London) has solved a decades-old mystery as to how Jupiter produces a spectacular burst of X-rays every few minutes.
The X-rays are part of Jupiter's aurora - bursts of visible and invisible light that occur when charged particles interact with the planet's atmosphere. A similar phenomenon occurs on Earth, creating the northern lights, but Goldilocks planets 'with a tilt' may develop more complex life

Planets which are tilted on their axis, like Earth, are more capable of evolving complex life. This finding will help scientists refine the search for more advanced life on exoplanets. This NASA-funded research is presented at the Goldschmidt Geochemistry Conference.
Since the first discovery of exoplanets (planets orbiting distant stars) in 1992, scientists have been looking for worlds wh
