Now that SpaceX has successfully and safely demonstrated the upright recovery of their Falcon 9 booster that flew to the edge of space and back on Dec. 21 – in a historic first – the intertwined questions of how did it fare and what lies ahead for the intact first stage stands front and center.

There are several space stories we’re anticipating for 2016 but one story might appear — to some — to belong in the realm of science fiction: sometime in the coming year Elon Musk will likely reveal his plans for colonizing Mars.
Early in 2015, Musk hinted that he would be publicly disclosing his strategies for the Mars Colonial Transport system sometime in late 2015, but then later said the announcement would come in 2016.
“The Mars transport system will be a completely new architecture,” Musk said during a Reddit AMA in January 2015, replying to a question about the development of MCT. “[I] am hoping to present that towards the end of this year. Good thing we didn’t do it sooner, as we have learned a huge amount from Falcon and Dragon.”
Big Rockets
As far as any details, Musk only said that he wants to be able to send 100 colonists to Mars at a time, and the “goal is 100 metric tons of useful payload to the surface of Mars. This obviously requires a very big spaceship and booster system.”
He has supposedly dubbed the rocket the BFR (for Big F’n Rocket) and the spaceship similarly as BFS.

Most online discussions describe the MCT as an interplanetary ferry, with the spaceship built on the ground and launched into orbit in one piece and perhaps refueled in low Earth orbit. The transporter could be powered by Raptor engines, which are cryogenic methane-fueled rocket engines rumored to be under development by SpaceX.
The future line-up of Falcon rockets is compared to the famous NASA Saturn V. The first Falcon Heavy launch is planned for 2015. Raptor engines may replace and upgrade Heavy then lead to Falcon X, Falcon X Heavy and Falcon XX. The Falcon X 1st stage would have half the thrust of a Saturn V, Falcon X Heavy and XX would exceed a Saturn V’s thrust by nearly 50%. (Illustration Credit: SpaceX, 2010)
The Challenge of Landing Large Payloads on Mars
While the big rocket and spaceship may seem to be a big hurdle, an even larger challenge is how to land a payload of 100 metric tons with 100 colonists, as Musk proposes, on Mars surface.
As we’ve discussed previously, there is a “Supersonic Transition Problem” at Mars. Mars’ thin atmosphere does not provide an enough aerodynamics to land a large vehicle like we can on Earth, but it is thick enough that thrusters such as what was used by the Apollo landers can’t be used without encountering aerodynamic problems such as sheering and incredible stress on the vehicle.

With current landing technology, a large, heavy human-sized vehicle streaking through Mars’ thin, volatile atmosphere only has about 90 seconds to slow from Mach 5 to under Mach 1, change and re-orient itself from a being a spacecraft to a lander, deploy parachutes to slow down further, then use thrusters to translate to the landing site and gently touch down.
90 seconds is not enough time, and the airbags used for rovers like Spirit and Opportunity and even the Skycrane system used for the Curiosity rover can’t be scaled up enough to land the size of payloads needed for humans on Mars.

NASA has been addressing this problem to a small degree, and has tested out inflatable aeroshells that can provide enough aerodynamic drag to decelerate and deliver larger payloads. Called Hypersonic Inflatable Aerodynamic Decelerator (HIAD), this is the best hope on the horizon for landing large payloads on Mars.
The Inflatable Reentry Vehicle Experiment (IRVE-3) was tested successfully in 2012. It was made of high tech fabric and inflated to create the shape and structure similar to a mushroom. When inflated, the IRVE-3 is about 10-ft (3 meter) in diameter, and is composed of a seven giant braided Kevlar rings stacked and lashed together – then covered by a thermal blanket made up of layers of heat resistant materials. These kinds of aeroshells can also generate lift, which would allow for additional slowing of the vehicle.
“NASA is currently developing and flight testing HIADs — a new class of relatively lightweight deployable aeroshells that could safely deliver more than 22 tons to the surface of Mars,” said Steve Gaddis, GCD manager at NASA’s Langley Research Center in a press release from NASA in September 2015.
NASA is expecting that a crewed spacecraft landing on Mars would weigh between 15 and 30 tons, and the space agency is looking for ideas through its Big Idea Challenge for how to create aeroshells big enough to do the job.
With current technology, landing the 100 metric tons that Musk envisions might be out of reach. But if there’s someone who could figure it out and get it done, Elon Musk just might be that person.

“There and back again,” said SpaceX CEO and founder Elon Musk after the amazing successful ‘Return to Flight’ launch of the firms Falcon 9 rocket and history making vertical return landing at Cape Canaveral, Fla, on Monday evening, Dec. 21.
For the first time in history, the first stage of a rocket blazing to orbit with a payload, separated successfully from the upper stage at high speed, turned around and then flew back to nail a successful rocket assisted upright touchdown back on the ground.
The upgraded “full thrust” SpaceX Falcon 9 blasted off Monday night, Dec. 21 at 8:29 p.m. from Space Launch Complex 40 on Cape Canaveral Air Force Station, Fla. carrying a constellation of ORBCOMM OG2 communications satellites to low Earth orbit.
“The Falcon Has Landed!” gushed exuberant SpaceX officials during a live webcast.
Read below what some excited eyewitnesses told Universe Today.

Accompanied by multiple shocking loud sonic booms, the 156 foot tall Falcon 9 first stage separated about 3 minutes into flight and landed successfully on the ground about 10 minutes later at the SpaceX Landing Zone 1 (LZ-1) complex at the Cape, some six miles south from pad 40.
The goal of SpaceX is to recover and eventually reuse the boosters in order to radically reduce the the cost of sending payloads and people to space, as often stated by SpaceX CEO Elon Musk.
My colleague and well known long time space photographer Julian Leek, remarked that the whole experience was fantastic!
“It was fantastic! You just would not believe the feeling,” space photographer Julian Leek told Universe Today. See his photos below.
“One of the best things I have seen since Apollo 11 liftoff!”
“It was one of the most spectacular space events I’ve seen,” said Jeff Seibert, another media photographer colleague.
“We felt like the rocket was coming down on top of us!”

See the dramatic landing in this SpaceX video taken from a nearby helicopter:
“Honestly it will be something I’ll always remember!” astronomy enthusiast Carol Higgins of the Mohawk Valley Astronomical Society of Utica NY, told Universe Today.
“Seeing that thing falling so fast toward Earth, then the engine fire to slow it down, then watching it falling closer to the Cape – my heart was pounding so fast and hard I wasn’t sure what was going to happen to me LOL!”
This morning, Dec. 22, media reps were taken on a boat trip along the Cape’s Atlantic Ocean coastline past Landing Zone 1 for a birdseye view of the Falcon 9 standing upright.
Two cranes from Beyel Bros Crane and Rigging were seen hoisting and moving the Falcon 9 first stage from the vertical to horizontal position at ‘Landing Zone 1’ according to Steven M Beyel.

The primary mission of the Falcon 9 launch was to carry a fleet of eleven small ORBCOMM OG2 commercial communications satellites to orbit on the second of two OG2 launches. All 11 satellites were successfully deployed at an altitude of about 400 mi (620 km) above Earth.
The next generation ORBCOMM OG2 satellites provide Machine – to – Machine (M2M) messaging and Automatic Identification System (AIS) services with capabilities far beyond the OG1 series.

Following a spectacular nighttime blastoff from Cape Canaveral, Fla, SpaceX has just successfully recovered and soft landed the 156 foot tall first stage of their Falcon 9 rocket back on the ground at the Cape – in a monumental and historic space feat that will reverberate around the world. This is a game changing moment that will alter the future of space travel.
WATCH the SpaceX webcast as the first stage lands, at about 31 minutes in the video:
Local area spectators cheered the launch and clearly saw the landing. They said several powerful sonic booms could be heard thundering loudly across the space coast. It was one of the most amazing sights they had ever seen, many folks said.
The upgraded SpaceX Falcon 9 launched a fleet 11 ORBCOMM OG2 communications satellites to orbit on Monday, Dec. 21 at 8:29 p.m. from Space Launch Complex 40 on Cape Canaveral Air Force Station, Fla.
The stunning liftoff and landing marked the Falcon 9 boosters ‘Return to Flight’ and is the first launch for SpaceX since the catastrophic mid-air destruction of the rocket six months ago on June 28, 2015 – after launching from the same pad as today – on a cargo mission for NASA bound for the International Space Station (ISS) and her six person crew.
The first stage landing, vertically at night, was apparently perfect and came off without a hitch by all accounts.
The Falcon 9 is equipped with four landing legs and four grid fins to enable the propulsive landing back on the ground at the Cape, once the first stage separates and relights a Merlin 1D engine.
About 3 minutes after liftoff and about 60 miles altitude, the spent first stage separated from the second stage which continued to orbit with the Orbcomm satellites.
While moving at extremely high speed of some 3000 mph, the rocket was then commanded to fire cold gas nitrogen attitude thrusters to reorient itself and to turn the vehicle around – its sort of like riding on a broomstick in a hurricane. It then conducted a boostback burn with a first stage Merlin 1D engine to create a reversed ballistic arc. Then it conducted a reentry burn and finally a landing burn above the ground at Landing Zone 1 at Cape Canaveral.
The quartet of side mounted landing legs were lowered into place in the final moments before touchdown.

The history making landing attempt of the boosters first stage took place back at the Cape at the SpaceX Landing Zone 1 site at about 8:39 p.m. EST after high altitude separation from the upper stage and around 10 minutes after launch.
The entire event from launch to landing was shown via a live SpaceX webcast.
The goal is to recover and eventually reuse the boosters in order to radically cut the cost of sending payloads and people to space, as often stated by SpaceX CEO Elon Musk.
But the key step to solve is you first have to recover the booster before you can even think about relaunching it. After its recovered it can then be thoroughly analyzed for the impact of aerodynamic stresses and the engine firings to determine the feasibility of refurbishment and reusability for relaunch.

Landing the Falcon 9 rockets first stage on land at SpaceX’s Landing Zone 1 (LZ-1) complex by a pinpoint propulsive soft landing was the secondary test objective. Landing Zone 1 is located some six miles south of launch pad 40 at Cape Canaveral.
Because of the proximity to populated areas, SpaceX required special approvals for the surface landing test from the Air Force and the FAA. And much of the military base and NASA installations have been evacuated for safety reasons. Media are also not allowed to watch and photograph from their customary locations on site at Cape Canaveral Air Force Station.
SpaceX has built Landing Zone 1 by renovating and refurbishing an abandoned area previously known as Space Launch Complex 13 (SLC-13).
Landing Zone 1 measures about 282 feet in diameter and is constructed of reinforced concrete. SpaceX has actually built several of the concrete landing pads for use as a landing site by the firms Falcon 9 as well as the triple barreled Falcon Heavy boosters which may debut in 2016.
Launch Complex 13 is a former U.S. Air Force rocket and missile testing range last used in 1978 for test launches of the Atlas ICBM and subsequently for operational Atlas launches.

The primary mission was to carry a payload of eleven small commercial communications satellites for Orbcomm on the second OG2 mission. They were fueled and stacked on the satellite dispenser and encapsulated inside the payload fairing.
All 11 of the refrigerator sized OG2 satellites were successfully deployed as planned at an altitude of about 400 mi (620 km). They joined the existing fleet of OG2 satellites.
The 380 pound (170 kg) satellites were deployed two at a time from the satellite dispenser during six separation events. The staggered deployment of the 170 kg comsats took place over about four minutes from 8:42 p.m. to 8 46 p.m. in order to place the constellation of spacecraft into the proper orbit.

This was the second and last OG2 launch for OrbComm. SpaceX has already notched one successful launch for Orbcomm when the first six Orbcomm OG2 satellites lifted off on July 14, 2014.
The ORBCOMM OG2 satellites provide Machine – to – Machine (M2M) messaging and Automatic Identification System (AIS) services.
Overall it was a wildly successful ‘Return to Flight’ and a historic day for SpaceX.

All is “GO” in the final hours of the countdown to leading up to tonight’s, Dec. 21, the high stakes blastoff of an upgraded SpaceX Falcon 9 rocket from Cape Canaveral on its ‘Return to Flight’ mission carrying a flock of commercial satellites to orbit that also features a breathtaking and history making flyback of the rockets first stage to a soft landing on the ground that could open a majestic era of Rocket Reusability – if all goes well.
Local space coast area residents might hear a sonic boom as the first stage propulsively steers back to Cape Canaveral.
The timing of Monday’s dramatic night launch of the 229 foot tall Falcon 9 rocket with a fleet of eleven commercial communications satellites for Orbcomm from Space Launch Complex-40 (SLC-40) on Cape Canaveral Air Force Station, Fla. has been revised to 8:29 p.m. EST.
Liftoff of the two stage Falcon 9 is slated for the opening of a newly revised and slight longer launch window which extends for five minutes under currently cloudy Florida skies.
You can watch the dramatic events unfold via a live SpaceX webcast available at SpaceX.com/webcast.
The SpaceX webcast is planned to start about 25 minutes before liftoff, beginning at approximately 8:10 p.m. ET on Dec. 21.

Air Force meteorologists are currently predicting an 80 percent chance of favorable weather conditions at launch time.
The SpaceX Falcon 9 rocket will deliver 11 satellites to low-Earth orbit for ORBCOMM, a leading global provider of Machine-to-Machine (M2M) communication and Internet of Things (IoT) solutions.
The history making landing attempt of the boosters first stage back at the Cape at Landing Zone 1 would come after high altitude separation from the upper stage and around 10 minutes after launch, and has gathered significant notoriety.
