Orion is Over Budget and May Need
Seven More Years Before Flying Crews (Source: Ars Technica)
At the request of Congress, the nonpartisan US Government
Accountability Office reviews the finances and management of federal
programs, and this week it released a study critical of NASA’s crew
capsule, Orion. Most worryingly, the 56-page report (PDF) regularly
draws parallels between the Orion program and another large overbudget
NASA project, the James Webb Space Telescope.
Although Orion has not yet experienced such dramatic increases in
costs, the spacecraft is now into its second decade of development.
NASA estimates that it will spend a total of $16 billion (£12 billion)
to ready Orion for its first crewed flight in April 2023. However, the
GAO review, signed by Director of Acquisition and Sourcing Management
Cristina T. Chaplain, did not find these numbers to be reliable.
Some of the major Orion concerns cited by the GAO study are well-known,
such as delays by NASA’s partner, the European Space Agency, in
building the service module that will help power Orion in space. Less
widely known, however, are significant cost overruns with Orion’s
primary contractor, Lockheed Martin. The GAO’s analysis of contractor
data found that the Orion program faces potential cost overruns of up
to $707 million by 2020. (7/28)

United Launch Alliance (ULA) successfully sent the sixth of the 421
configuration of the company’s Atlas V launch vehicle into the morning
skies. The payload for Thursday’s flight was a classified satellite for
the National Reconnaissance Office (NRO). As was a classified mission
for the NRO, the upper stage burned for an unknown amount of time to
send the satellite into an undisclosed orbit. (7/28)
Genovation's GXE Breaks All-Electric
Land Speed Record – Reaches 205.6 mph (Source: Genovation)
Genovation today announced that it has made history by breaking the
land speed record for a street legal all-electric vehicle with the
Genovation Extreme Electric car (GXE). The GXE reached the record
breaking speed of 205.6 mph during supervised tests with Johnny Bohmer
Racing at Space Florida’s Shuttle Landing Facility at the Cape
Canaveral Spaceport. The record was certified by the International Mile
Racing Association (IMRA). The previous record, which also was held by
Genovation, stood at 186.8 mph. (7/28)
Space Radiation May Cause Heart Disease
(Source: Air & Space)
Of all the risks facing astronauts on a trip to Mars, radiation
generally tops the worry list. It’s long been known that venturing
outside Earth’s protective magnetic field—to the moon or Mars—exposes
astronauts to a steady bombardment from heavy cosmic rays that can
damage DNA and increase long-term cancer risk. And that’s not even
considering the acute risk of radiation sickness if space travelers
were caught in a strong solar storm without some kind of shielding.
In the past, the effects of radiation on astronauts’ cardiovascular
health hasn’t gotten as much attention as the risk from cancer. That’s
why a study published today in Scientific Reports by Michael Delp of
Florida State University and his colleagues is troubling: Apollo
astronauts—the only humans ever to venture into deep space—have died
from cardiovascular disease at a rate four to five times higher than
other astronauts. This is the first time anyone has looked at mortality
of the Apollo astronauts as a separate group. (7/28)
Dream Chaser Spacecraft to Begin Phase
Two Flight Testing (Source: SNC)
Sierra Nevada Corp.’s Dream Chaser full-scale, flight test vehicle is
ready for transportation to NASA’s Armstrong Flight Research Center
(AFRC) in California where Phase Two flight tests will be conducted in
coordination with Edwards Air Force Base (AFB). Dream Chaser program
upgrades and initial hardware testing were completed at the Louisville,
Colorado spacecraft assembly facility, and within the next several
weeks the same Dream Chaser vehicle that conducted Phase One flight
testing will arrive at NASA’s AFRC.
Upon arrival, SNC will begin a series of pre-flight ground evaluations
to verify and validate the vehicle’s system and subsystem designs.
After successful completion of all ground testing, Dream Chaser will
begin its Phase Two free-flight testing. These activities are being
conducted through a Space Act Agreement with NASA’s Commercial Crew
Program (CCP). (7/28)

Comet Lander Philae Says Goodbye as
Communications Are Cut (Source: Engadget)
Farewell Philae, it was a short but wild ride. In February, mission
controllers said goodbye to the comet lander, but kept comms open with
mother ship Rosetta on the slight chance it might wake up. "It's cold
& dark on #67P ... but I won't give up just yet," Philae tweeted
hopefully. However, controllers elected to cut Rosetta's "ESS" lander
radio at 5AM ET today to preserve its precious remaining power.
At nearly 520 million km (323 million miles) from the Sun, the probe is
losing power at the rate of 4 watts a day and needs to keep working for
another two months. On September 30th it'll crash into the surface of
the comet, but take numerous final photos and measurements on the way
down. (7/28)
India to Appeal Against Hague
Tribunal’s Verdict on Antrix-Devas Deal (Source: Hindustan Times)
India will appeal against the verdict of the Hague tribunal in
Antrix-Devas deal case, in which the international court had declared
the annulling of the contract as “unfair” and “inequitable” and asked
it to pay a huge amount as compensation. “We will appeal against the
verdict at Hague (tribunal),” said AS Kirankumar, secretary, Department
of Space. He, however, declined to comment any further on the issue.
India lost the arbitration case in a Permanent Court of Arbitration
(PCA) tribunal based in the Hague over its space marketing PSU Antrix
Corp, annulling a contract with Bengaluru-based private multimedia firm
Devas. The tribunal ruled that the Indian government had acted
“unfairly” and “inequitably” in cancelling the contract involving use
of two satellites and spectrum. (7/28)
Say Hello to Earth's Space
Weather-Fighting Robot (Source: Inverse)
Today was the first day on the job for a 1,200-pound satellite dubbed
the Deep Space Climate Observatory’s — DSCOVR for short — that took
over as the primary space tech that helps protect our planet from
hostile space weather. NOAA’s space weather forecasts shifted to being
exclusively supported by DSCOVR data instead of using data primarily
from the 19-year-old Advanced Composition Explorer.
Why is this such a big deal? Space weather means a lot for the world’s
electrical grids, mostly. For the uninitiated, the term refers to the
movement and behavior of solar winds; coronal mass ejections from the
sun; varying conditions in the magnetosphere and ionosphere; and other
strange cosmic bits hurtling through the vacuum of space. It’s
basically how high-energy events interface with the electrical and
magnetic parts of Earth’s atmosphere. (7/28)
One of NASA's Biggest Concerns Comes
to Light in Cleveland (Source: Inverse)
One of the biggest concerns for NASA is that it won’t be able to send
U.S. astronauts into space after 2018. On Thursday, the NASA Advisory
Council held a public meeting to deliver a series of reports about the
status of the agency, and offered an update on Human Exploration and
Operations. Basically, time is running out for the space agency to find
another way to get American astronauts to space.
America needs to let the Russians know if it’s hitching a ride aboard
the Soyuz spacecraft before the year is out, or else we may see a
temporary — or worst case scenario, permanent — end of a U.S. presence
aboard the International Space Station. The solution? Presently, it’s
to work with commercial spaceflight companies like SpaceX and Boeing
after 2018, while NASA continues development of the Space Launch
System, which should have its first launch in November 2018. (7/28)
Western U.S. Saw An Amazing Light Show
Last Night, Courtesy Of China (Source: NPR)
Maybe it was a meteor? Or space junk? People on the West Coast weren't
sure what the bright object was that streaked across the sky Wednesday
night, but they knew it was spectacular. Now comes word that the object
— which separated into bright fragments — was a stage of China's large
new rocket. Americans who spotted the flaring object Wednesday night
could be forgiven for not knowing that.
The light show appeared in skies over the western U.S. around 9:30 p.m.
PT, sparking a flood of reports to meteor-monitoring groups, a flurry
of tweets and a number of striking videos. While first-person accounts
on Meteorite News differed, some details were constant: The string of
objects moved from west to east, with alternating colors and a bright
trail.
The object was the second stage of China's Chang Zheng 7 rocket that
was launched on June 25, according to astronomer Jonathan McDowell of
the Harvard-Smithsonian Center for Astrophysics, who cites confirmation
from the Space-Track organization and the Joint Space Operations
Center. This was the first CZ-7 launched, McDowell says, adding that
it's rare for objects of more than 5 tons to re-enter Earth's
atmosphere. (7/28)
Apollo Astronauts Dying of Heart
Disease at 4-5X the Rate of Counterparts (Source: Ars Technica)
Deep-space travel takes a toll on the body—and it’s apparently
something you can’t moon-walk off. Apollo astronauts who have ventured
out of the protective magnetosphere of mother Earth appear to be dying
of cardiovascular disease at a far higher rate than their
counterparts—both those that have stayed grounded and those that only
flew in the shielding embrace of low-Earth orbit.
Though the data is slim—based on only 77 astronauts total—researchers
speculate that potent ionizing radiation in deep space may be to blame.
That hypothesis was backed up in follow-up mouse studies that provided
evidence that similar radiation exposure led to long-lasting damage to
the rodents’ blood vessels. The study, while not definitive, may add an
extra note of caution to the potential hazards of future attempts to
fly to Mars and elsewhere in the cosmos. (7/28)
