The U.S. Air Force might need to continue using Russian-made RD-180 engines for the time being, despite congressional wishes otherwise, crimping Aerojet Rocketdyne’s EELV ambitions.

Glen Fountain, New Horizons project manager at the Johns Hopkins University Applied Physics Laboratory, said Monday the spacecraft will hit its 60 x 90-mi. box “almost at the center of it” and right on time.

Planetary scientists are getting their first detailed look at the terrain on Pluto, as the New Horizons spacecraft closes in for a fast flyby on July 14.

The importance of satellite and space technology for environmental monitoring purposes was highlighted by the UAE Space Agency at the Eye of Earth Summit 2015 in Abu Dhabi.

The recent ISS cargo failures are not slowing down the momentum toward research focus, especially when it comes to space commercialization.

Four NASA astronauts, all veterans with experience aboard the International Space Station, space shuttle or Russian Soyuz spacecraft, have been named to train to fly aboard the first U.S. commercial crew missions, tentatively planned for 2016-17.

Details of the critical technology at the core of an innovative hybrid hypersonic propulsion system for air and space systems have been unveiled for the first time by its British-based developer, Reaction Engines.

How to get to Mars is only part of the question. NASA calls for ideas on the best places to actually land, optimal also for living, mining resources and conducting scientific exploration.

Russia’s Progress 60 resupply vehicle delivered supplies to ISS crew, along with a sense of relief to space handlers worldwide in the aftermath of a spate of resupply mission launch failures.

Timing flaw put temporary shutdown on New Horizon's data collection mission at Pluto. Science operations will resume July 7.

Spacecraft controllers and engineers are pushing to restore science operations on New Horizons, after an on-board anomaly took the probe offline and out of communications on July 4.

The UAE Space Agency continued its efforts to strengthen international strategic partnerships, including improving the UAE's role and place within the international space sector, by organising an official Agency visit to the United States.

Lapse in Ex-Im bank assistance could hurt Boeing in the long term, and the general aviation community sooner; Former NASA chief provides another perspective on SpaceX’s commercial viability.

The same instrument that has been scanning ahead for collision danger to the fast-moving probe is also revealing new details about Pluto’s surface, including a row of mysterious dark spots along the equator.

What will happen when New Horizons hurtles past the icy dwarf planet and its five moons on July 14?

New Horizons probe flyby of Pluto, almost 15 years in the making, had to overcome both technical and bureaucratic challenges.

New Horizons has a long trajectory and it is not over yet.

New Horizons expects successful transmission of data collected at Pluto back to Earth, but space debris could create problems.

The spacecraft is in the midst of taking “hundreds” of images and science measurements, “about half” of them programmed for the day that surrounds closest approach to Pluto at 7:49:57 a.m. EDT, according to Leslie Young, the deputy project scientist and Pluto-encounter planning lead.

The concept for low-energy planetary entry is described as similar to “throwing an air mattress into the atmosphere.”

When massive Stratolaunch program begins to wind down, Scaled Composites promises a return to the Rutan days of smaller, fast-paced projects that result in flight testing of aviation breakthroughs.

With Proton and Falcon 9 sidelined and Ariane 5 booked into 2017, commercial fleet operators question how much longer the status quo can continue.

Scientists hope the New Horizons Pluto probe will turn a lifetime of preparation into a once-in-a-lifetime glimpse of the most remote object ever visited by humans.

Scientists involved in exploration of the Pluto system have to take the long view, after waiting almost a decade just to get there.

The spacecraft is fitted out with a payload package of small but powerful instruments, which will have one quick shot to do their job before flying past Pluto.
