NORAD Tracks Santa (Source:
Florida Today)
It's the time of year when space-based military assets on the lookout
for national security threats engage in a happier form of surveillance:
tracking Santa. Continuing a tradition that dates to 1955, the North
American Aerospace Defense Command, or NORAD, promises to alert
families around the globe to the whereabouts of Santa and his reindeer,
now with the aid of radars, satellites and fighter jets.
Visit noradsanta.org to follow the countdown to the journey's Dec. 24
start. How does NORAD track Santa? One method utilizes infrared sensors
housed on satellites more than 22,000 miles up, whose primary mission
is to provide warnings of missile launches. In a strange mingling of
defense technology and innocent holiday merriment, NORAD says those
sensors are ideal for spotting Rudolph's glowing nose.
"Rudolph's nose gives off an infrared signature similar to a missile
launch," the tracking Web site explains. "The satellites detect
Rudolph's bright red nose with no problem." (12/20)
Asteroid Mission Update
(Source: Florida Today)
NASA officials met last week to review two options for how to
robotically retrieve an asteroid that astronauts could visit by the
mid-2020s, but couldn't settle on one as planned. Associate
Administrator Robert Lightfoot deferred a decision on whether to try to
capture a small, free-floating asteroid or to pry a boulder from a
larger asteroid.
"It was a lot to digest," Lightfoot told reporters about the meeting.
"I need to get some more clarification on some areas." Lightfoot now
expects to choose the preferred option for the Asteroid Redirect
Mission early next year, in advance of a more comprehensive review
planned in late February that will officially commit to a mission
strategy and cost.
The goal for any robotic mission is to steer an asteroid to an orbit
near the moon where astronauts could reach it an Orion spacecraft
launched from KSC by the agency's Space Launch System rocket. Crews
could perform that mission in a few weeks, but would need four years to
visit an asteroid in its "native" orbit. (12/20)
The New Space Rescue Mission: Saving
NASA (Source: Houston Chronicle)
The legendary Christopher Columbus Kraft, who lived up to his namesake
by leading NASA to the moon, has grown old. Severe lines crease his
face, and Kraft’s fingers have gnarled. Earlier this year, just before
his 90th birthday, sciatica forced him to adopt a cane and, more
gallingly, to give up golf. Still, he can accept what time has done to
him. It’s harder to make peace with what’s become of NASA.
In the 1960s, President Kennedy gave Kraft, the agency’s first flight
director, and NASA’s other leaders a blank check and told them to
boldly go. They did. The Apollo guys chomped cigars and called the
shots. Those in charge today no longer sit behind flight control
consoles, conquering space. They’re at desks in Washington, D.C.,
politicians and bureaucrats who micromanage the agency’s budget and
repeatedly move the goalposts. Click here.

Can NASA's Orion Program Reinvigorate
Human Spaceflight? (Source: CS Monitor)
NASA's human spaceflight program has been struggling with the same
problem since the Apollo program: It doesn't have enough money to do
the really exciting stuff. Orion's mission to Mars is NASA's latest
attempt to address the issue, but the numbers still might not add up.

NASA Releases Video of Orion Reentry
(Source: SpaceFlight Insider)
Upon completing its two-orbit voyage into space, NASA’s new crew-rated
spacecraft, Orion, returned home at speeds reaching some 20,000 miles
(32,187 kilometers) an hour. What would an astronaut see from his or
her position seated within the capsule-shaped spacecraft? NASA placed a
camera inside the Orion that carried out the Dec. 5 Exploration Flight
Test 1 (EFT-1) mission – and the footage it provided – helped answer
that very question. Click here.

'Broomfield Scale' Confronts Cosmic
Threats (Source: Daily Camera)
It is at the Secure World Foundation where work is progressing toward
creating a cooperative, coordinated global response to the potential of
a "near-Earth object," such as an asteroid, imperiling this planet's
future. At a two-day workshop in September hosted there at the request
of the International Asteroid Warning Network — and with little outward
fanfare — a new tool was developed that could be a key component in
planetary preparations for facing the unthinkable.
They've dubbed it the Broomfield Hazard Scale. "The argument was that
we've named all our (hazard) scales after places, and this conference
was in Broomfield, the Secure World Foundation is here, Colorado is a
major space state ... and that it had a kind of neutral quality to it.
It was not the Washington scale, or the Houston scale — it was a scale
that represented not only a place, but something the place had
facilitated."
The proposed Broomfield Scale is a six-step qualitative hazard scale,
in tabular form, based on a near-Earth object's size and potential
kinetic energy in tons of TNT equivalency, pairing that with the
potential range of destruction that might ensue. The range depicted
extends from the "visible fireball" that would be evident from a
"Class-1" object less than 10 meters in diameter with a kinetic energy
of less than 50 kilotons, to a "Class 6" intruder more than 600 meters
in size, which would threaten "global destruction." (12/19)

Mars Tech: From Ion Thrusters to Laser
Communications (Source: CS Monitor)
Rockets leaving launchpads are the most visible signs that a deep-space
human exploration program is under way. But those missions are the
result of behind-the-scenes engineering that provides new technologies.
To get humans to Mars, NASA is going to have to develop a variety of
new technologies. But these technologies can also be used for other
purposes, such as robotic science missions or more-advanced commercial
satellites. Click here.

Venus Express Ends Eight Year Mission
(Source: SEN)
ESA’s Venus Express has finally ended its eight-year mission. The
spacecraft exhausted its fuel during a series of thruster burns earlier
this year and will now naturally sink deeper into the atmosphere over
the coming weeks. Since arriving at Venus in 2006, Venus Express has
conducted a detailed study of the planet and its atmosphere.
With propellant for its propulsion system running low, the spacecraft
was tasked in mid-2014 with a daring aerobraking campaign, during which
it dipped progressively lower into the atmosphere on its closest
approaches to the planet, allowing an exploration of previously
uncharted regions of the atmosphere. (12/20)
Indian Hitchhikers Lost, Seek a Legal
Guide to the Galaxy (Source: Times of India)
Several startups coming up in the Indian space sector are feeling
hampered by the lack of a legal and regulatory framework that can help
support and encourage new ventures. These companies, both early stage
ventures and some established private companies that develop a range of
solutions from frugally built spacecraft to custom-made solutions are
looking for support that can help spur innovation and publicprivate
partnerships, which can help reduce imports and support growing startup
activity in the sector. Click here.

Working Toward a Warp Drive: In an
Omaha Garage Lab (Source: Omaha.com)
You might call David Pares a dreamer, though what he’s doing goes far
beyond the realm of online chatter. Some guys spend their spare time
restoring automobiles, devoting garage space to motionless Corvettes
and Camaros. Pares is making his own warp drive. To hear him and his
small team of supporters tell it, something weird is happening out here
in the garage. “The compression of the fabric of space,” Pares says
matter-of-factly.
On average, Pares spends a couple of hours a day here almost every day
of the week. To bend the fabric of space, he sits in front of a tray of
instruments, twisting knobs and glancing every now and then into a
Faraday cage, where a 3.5-pound weight hangs inside an electrically
isolated case. Outside the case hangs a strange instrument made up of
V-shape panels with fractal arrays on the surfaces. The instrument is
the latest version of what Pares believes is the world’s first
low-power warp drive motor.
He turns around and points to the back of his garage door, where a red
laser — beamed at the weight and reflected back against the door to
demonstrate the movement happening in the case — drifts from its
original spot. Slowly, in incremental amounts, the weight is drawn
toward the V-shape motor. "You’re not supposed to be able to do this,”
Pares says. At just 100 watts of power, he claims an electrical field
created by his arrays is ever so slightly condensing space in front of
the motor, the way you’d squeeze coils on a Slinky. Click here.
