Skywatcher and satellite tracker, Ralf Vandebergh of the Netherlands, has caught an over flight of the U.S. Air Force secretive X-37B space plane, also known as Orbital Test Vehicle – 5.
Vandebergh reports that he has been hunting for the OTV-5 for months and saw it visually in May.
“When I tried to observe it again mid June, it didn’t meet the predicted time and path. It turned out to have maneuvered to another orbit. Thanks to the amateur satellite observers-network, it was rapidly found in orbit again and I was able to take some images on June 30 and July 2,” Vandebergh explains.
Beyond expectations
The OTV-5’s recent pass was almost overhead, Vandebergh adds.
The OTV is a small version of the classic space shuttle. “It is really a small object, even at only [186 miles] 300 kilometers altitude, so don’t expect the detail level of ground based images of the real space shuttle.”
Considering this, the images Vandebergh says succeeded beyond expectations. “We can recognize a bit of the nose, payload bay and tail of this mini-shuttle with even a sign of some smaller detail.”
The Images were taken through a 10 inch F/4,8 aperture Newtonian telescope with an Astrolumina ALccd 5L-11 mono CMOS camera. Tracking was fully manually through a 6×30 finderscope, Vandebergh explains.

Classified duties
The secretive mission of the U.S. Air Force X-37B mini-space plane has winged past 666 days of flight. This robotic drone is performing classified duties during the program’s fifth flight.
This Orbital Test Vehicle (OTV-5) was rocketed into Earth orbit on September 7, 2017 atop a SpaceX Falcon 9 booster from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

The missions of the X-37B space planes are carried out under the auspices of the Air Force Rapid Capabilities Office, and mission control for OTV flights are handled by the 3rd Space Experimentation Squadron at Schriever Air Force Base in Colorado. This squadron oversees operations of the X-37B Orbital Test Vehicle and is tagged as the Air Force Space Command’s premier organization for space-based demonstrations, pathfinders and experiment testing, gathering information on objects high above Earth and carrying out other intelligence-gathering duties.
And that may be a signal as to what the robotic craft is doing — both looking down at Earth and upward.

Flight-duration record
Each X-37B/OTV mission has set a new flight-duration record for the program:
OTV-1 began April 22, 2010, and concluded on Dec. 3, 2010, after 224 days in orbit.
OTV-2 began March 5, 2011, and concluded on June 16, 2012, after 468 days on orbit.
OTV-3 chalked up nearly 675 days in orbit before finally coming down on Oct. 17, 2014.
OTV-4 conducted on-orbit experiments for 718 days during its mission, extending the total number of days spent in space for the OTV program at that point to 2,085 days. It was launched in May 2015 and landed in May 2017.

On-orbit testing
On this latest clandestine mission of the space plane, all that’s known according to Air Force officials is that one payload flying on OTV-5 is the Advanced Structurally Embedded Thermal Spreader, or ASETS-II.
Developed by the U.S. Air Force Research Laboratory (AFRL), this cargo is testing experimental electronics and oscillating heat pipes for long duration stints in the space environment.
According to AFRL, the payload’s three primary science objectives are to measure the initial on-orbit thermal performance, to measure long duration thermal performance, and to assess any lifetime degradation.

Tarmac touchdown
Exactly when the OTV-5 space plane will land is unknown.
The last Air Force’s X-37B Orbital Test Vehicle mission touched down at NASA’s Kennedy Space Center Shuttle Landing Facility May 7, 2017 – a first for the program. All prior missions had ended with a tarmac touchdown at Vandenberg Air Force Base in California.
Several website postings say that the sixth mission, X-37B OTV-6, is planned for this year on a United Launch Alliance Atlas-5(501) rocket. Launch would be from Cape Canaveral Air Force Station’s Space Launch Complex-41.

Reusable vehicles
The classified X-37B program “fleet” consists of two known reusable vehicles, both of which were built by Boeing.
The X-37B Orbital Test Vehicle was fabricated at several Boeing locations in Southern California, including Huntington Beach, Seal Beach and El Segundo. The program transitioned to the U.S. Air Force in 2004 after earlier funded research efforts by Boeing, NASA and the Defense Advanced Research Projects Agency.
Looking like a miniature version of NASA’s now-retired space shuttle orbiter, the military space plane is 29 feet (8.8 meters) long and 9.6 feet (2.9 m) tall, with a wingspan of nearly 15 feet (4.6 m).
The X-37B space plane has a payload bay of 7 feet (2.1 meters) by 4 feet (1.2 meters), a bay that can be outfitted with a robotic arm. X-37B has a launch weight of 11,000 lbs. (4,990 kilograms) and is powered on orbit by gallium-arsenide solar cells with lithium-ion batteries.

Milestone for the program
Prior to launch of OTV-5, Randy Walden, the director of the Air Force Rapid Capabilities Office said there were many firsts on this mission, making it a milestone for the program. “It is our goal to continue advancing the X-37B OTV so it can more fully support the growing space community.”
The Air Force also noted that the fifth OTV mission was launched into, and will be landed from, a higher inclination orbit than prior missions to further expand the X-37B’s orbital envelope.

Ahead of the 50th anniversary of the U.S. Moon landing, 60% say the space program has provided enough benefit to the country to justify its cost, while 38% do not consider the country’s expenditures on the space program warranted.
Most Americans say it is important for the space program to monitor objects including asteroids, comets, and other objects that could impact the Earth, as well as scientifically research the universe, our solar system, and the Earth.
On the other hand, the establishment of permanent human settlements on other planets or developing an American military presence in space are not considered priorities.

Robots over humans
Americans prefer a space program that focuses on potential asteroid impacts, scientific research and using robots to explore the cosmos over sending humans back to the Moon or on to Mars, the poll shows.

Reports Melissa Rice, a planetary geologist at Western Washington University, Bellingham, Washington: “Curiosity is currently near the top of Harlaw Rise, having made a slight diversion from the southward drive through the clay-bearing unit to explore the nice exposures of rocks on this hill.”
A recent plan called for Curiosity to investigate two rock targets in front of the rover: “Perth” and “Aberdeen.”

Closer look
There is only enough time in this plan to put the arm on one of these two targets, Rice adds, so Perth will get a closer look with the Mars Hand Lens Imager (MAHLI) microscopic imager and Alpha Particle X-Ray Spectrometer (APXS) instrument, and “Aberdeen” will get shot by the Chemistry and Camera (ChemCam) laser.
“The Mastcam cameras will document both targets. After that, Curiosity will make a short drive further up the hill to a spot where both of these rock types might be better exposed,” Rice points out.

Name game
“Why do we give names like “Perth” and “Aberdeen” to Curiosity’s rock targets? How does the largest city in Western Australia end up right next to a Washington State timber town? As a Long-Term Planner for the Curiosity science team, one of my responsibilities is to keep track of the names that the team uses, and to make sure that they fit within the theme for this portion of the rover’s traverse,” Rice explains.
Curiosity is currently in a region of the team’s geologic map called the Torridon Quadrangle, named after a village in the Northwest Highlands of Scotland, Ricet adds, which is near an important geological formation called the Torridonian Supergroup.

“Therefore, all of the names assigned to targets in this region of Curiosity’s traverse come from landforms, geologic formations, and towns in that part of Scotland. So the namesakes of today’s ‘Perth’ and ‘Aberdeen’ rock targets on Mars are the same as those of all the other Perths and Aberdeens out there: Perth, Scotland, and Aberdeen, Scotland,” Rice says.
