China’s Long March-5 Y2 carrier rocket arrives at launch site

WENCHANG, Hainan, April 30 (Xinhua) — China’s Long March-5 Y2 carrier rocket arrived at the launch base in Hainan, south China, on Sunday.

The launch vehicle departed from northern China’s Tianjin on April 24 and sailed 1,670 nautical miles before reaching Wenchang, Hainan Province.

The rocket will be used in the launch of the Shijian-18 communication satellite in June.

The Long March-5 carrier rocket made its maiden flight in Wenchang on Nov. 3, 2016.

SpaceX Falcon 9FT w/NROL-76 Launch Webcast

SpaceX is targeting launch of NROL-76 from historic Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. The two hour launch window opens on Sunday, April 30, at 7:00 a.m. EDT, or 11:00 UTC. A backup launch window opens on Monday, May 1, at 7:00 a.m. EDT, or 11:00 UTC.

Following stage separation, Falcon 9’s first stage will attempt to land at SpaceX’s Landing Zone 1 (LZ-1) at Cape Canaveral Air Force Station, Florida.

China’s Long March-5 Y2 carrier rocket leaves for launch site

TIANJIN, April 24 (Xinhua) — China’s Long March-5 Y2 carrier rocket departed northern China’s Tianjin Port for the launch base in southern Hainan Monday.

Monday is also China’s second Space Day, which was chosen to mark the anniversary of the country’s first satellite launch Dongfanghong-1 in 1970.

Carried by special rocket-carrying ships, the rocket will arrive in Wenchang, Hainan Province, for the scheduled launching of the Shijian-18 communication satellite in June.

The Long March-5 Y3 carrier rocket is planned to carry the Chang’e-5 lunar probe in 2017.

As the country’s strongest carrier rocket, the Long March-5 has a payload capacity of 25 tonnes in low Earth orbit and 14 tonnes in geostationary orbit. Its carrying capacity is about 2.5 times that of the current main model Long March carrier rockets.

The Long March-5 carrier rocket made its maiden flight in Wenchang on Nov. 3, 2016.

National Security After the SpaceX Explosion

Congress’s demand to cease using Russian engines may leave the military dependent on unproven rockets.

The explosion of an unmanned SpaceX rocket after liftoff at Cape Canaveral in Florida on Sunday was a graphic reminder of why U.S. national space policy requires that there betwo independent means of launching satellites for national-security missions: in case one launch system fails.

SpaceX, headed by Elon Musk, is contracted to resupply the International Space Station. Critics who are unhappy about the use of Russian rocket engines for national-security launches have campaigned to get SpaceX involved in those missions. But the failure of its Falcon 9 version 1.1 rocket should give everyone pause about jettisoning a dependable arrangement vital to U.S. security.

Current U.S. space policy is implemented by buying both the Atlas V and Delta IV rockets from the United Launch Alliance, a joint venture of Lockheed Martin and Boeing. Both rockets have a 100% success record—83 launches without failure.

Yet Congress is on the verge of passing legislation—the fiscal 2016 National Defense Authorization Act—that will put U.S. space policy at considerable risk.

Why Elon Musk’s space rockets are so much more promising than Jeff Bezos’ right now

This year is shaping up to be an extremely exciting time for the future of commercial spaceflight, which will be built upon the backbone of revolutionary 21st-century rockets. The private American space companies Blue Origin and SpaceX are paving the way.

SpaceX-United Launch Alliance push for re-use in rockets is part of larger space trend – Denver Business Journal

Colorado Springs — The images of a SpaceX rocket booster toppling over and exploding after nearly landing on an ocean barge isn’t just a spectacle. It’s also the highest-profile example of a trend reshaping aerospace.

Pushed by tight budgets and growing concern about orbits increasingly littered with debris from past missions, companies have started getting serious re-using things where it makes sense and designing space systems to be sustainable, not single-use and disposable.

Re-use in space emerged as a major theme of this week’s annual Space Symposium industry gathering in Colorado Springs.

SpaceX, or Space Exploration Technologies Corp., Elon Musk’s rocket company based in Hawthorne, California, has made the biggest splash about re-using technology by trying to land its spent rocket booster on a floating barge in the ocean so it can explore what salvageable parts can be used again.

But SpaceX isn’t alone in looking to re-use rocket parts.

At the Space Symposium, Centennial-based United Launch Alliance revealed its designs for a new line of rockets it plans to build, called Vulcan, and it features re-using its booster engines in an effort to bring launch costs down to $100 million.

Rather than land a booster, ULA plans to have the first-stage rocket engines descend back into the atmosphere on a parachute to be caught by a helicopter and recovered for later refurbishing and re-use.

Why We Don’t Have an SST | Flight Today | Air & Space Magazine

In the politics of supersonic transport, “boom” let to bust.

Ask why there was no replacement for the Concorde, which retired in 2003, and people will tell you that supersonic commercial flight is uneconomical. It’s not necessarily true. A supersonic transport (SST) is within the state of the art, but attempts to build one have been misdirected by politics and entrenched business interests, with a dash of class warfare.

Can A ‘Planet-Like Object’ Start Its Life Blazing As Hot As A Star?

Nature once again shows us how hard it is to fit astronomical objects into categories. An examination of a so-far unique brown dwarf — an object that is a little too small to start nuclear fusion and be a star — shows that it could have been as hot as a star in the ancient past.

The object is one of a handful of brown dwarfs that are called “Y dwarfs”. This is the coolest kind of star or star-like object we know of. These objects have been observed at least as far back as 2008, although they were predicted by theory before.
