Update for 10:22 a.m. PT Jan. 22: Blue Origin, the space venture founded by Amazon billionaire Jeff Bezos, says it’s scheduling the next uncrewed test flight of its New Shepard suborbital space ship for Wednesday.

Liftoff had been postponed several times, due to technical concerns as well as worries about high winds at the West Texas launch site.

This week alone brought two schedule updates, first on Sunday:

We have decided to push our #NewShepard launch attempt tomorrow. High winds expected in the area and one vehicle open issue. Updated launch target to come tomorrow – follow here for updates #NS10 — Blue Origin (@blueorigin) January 20, 2019

And again on Monday:

More heavy winds in the forecast for tomorrow, so we are now targeting Wednesday 1/23 for the #NewShepard #NS10 launch. — Blue Origin (@blueorigin) January 21, 2019

Today, Blue Origin confirmed that all systems were go for Wednesday:

We are go for launch tomorrow. Weather looking good. Targeting liftoff at 8:50 am CST / 14:50 UTC. Follow live on https://t.co/7Y4The9OmR and check out the @NASA payloads flying with us https://t.co/XL8Yu1hKmI pic.twitter.com/pkRpcUVJQB — Blue Origin (@blueorigin) January 22, 2019

Previously: Blue Origin is rescheduling the 10th uncrewed test flight of its New Shepard suborbital spaceship, more than a month after a ground infrastructure issue at the company’s West Texas launch facility forced a postponement.

The flight’s main goal is to test the systems on New Shepard in preparation for flying passengers later this year. But even though the crew capsule won’t be carrying any crew this time around, it won’t be empty:

Blue Origin plans to fly eight NASA-funded science payloads. The payloads have received funding from NASA’s Flight Opportunities Program and are good to go despite the partial government shutdown. “Blue supports NASA’s Flight Opportunities program and its role in perfecting technology for a future human presence in space,” Blue Origin said in a news release.

The flight profile for a typical New Shepard flight test involves firing up the craft’s booster to send the crew capsule to heights above 62 miles (100 kilometers), crossing the space frontier in the process. After separation, the booster flies itself back to a landing, while the capsule deploys parachutes and floats back to Earth.

There are a few minutes of weightlessness at the top of the ride, and based on webcam views from previous tests, there are great views of the curving Earth beneath the black sky of space.

This 10th flight test was initially planned for Dec. 18, but Blue Origin said it had to delay the launch due to a ground infrastructure issue and other concerns that cropped up. Several other postponements followed.

The company hasn’t provided details, but outside sources who are familiar with launch procedures have speculated that the ground infrastructure issue had to do either with the system that provides liquid hydrogen and liquid oxygen for the booster, or with the range tracking system.

Here’s the lineup of payloads for Mission 10, as described by Blue Origin:

Carthage College Space Sciences Program: The Modal Propellant Gauging experiment led by Kevin Crosby is a joint effort with the NASA Kennedy Space Center Cryogenics Laboratory. It demonstrates a way to measure fuel levels in microgravity by using sound waves.

Controlled Dynamics Inc . : The Vibration Isolation Platform (VIP) aims to separate payloads from the normally occurring vibrations experienced during spaceflight. The apparatus should give researchers a clear understanding of microgravity’s effects on their research results. The team is led by Scott Green. VIP also flew aboard Virgin Galactic’s VSS Unity.

Johns Hopkins University Applied Physics Lab: On its second flight with Blue, the EM Field experiment will observe and collect data on the naturally occurring electromagnetic fields inside and outside New Shepard during the launch. Principal investigator Todd Smith will use this experiment to determine how global measurements of Earth’s electromagnetic field can be conducted in the future.

NASA Goddard Space Flight Center: Cooling tightly-packed electronics onboard a spacecraft can be challenging, and many solutions have not been able to undergo robust testing. Principal investigator Franklin Robinson will test one of these solutions in his Flow Boiling in Microgap Coolers experiment.

University of Central Florida: Two teams led by Josh Colwell and Addie Dove have planetary science payloads on New Shepard. The Collisions Into Dust Experiment (COLLIDE) aims to understand how dust particles react after surface contact during exploration missions to places such as the moon, Mars and asteroids. The Collection of Regolith Experiment (CORE) addresses the unique challenge of collecting and analyzing material samples in microgravity. COLLIDE also flew aboard VSS Unity.

University of Florida: Rob Ferl and Anna-Lisa Paul are adapting technology designed for the International Space Station to suborbital uses with their experiment, Validating Telemetric Imaging Hardware for Crew-Assisted and Crew-Autonomous Biological Imaging in Suborbital Applications. By recalibrating the way data is collected, the experiment will enable more biological research on suborbital missions. This experiment also flew aboard VSS Unity.

In addition to its suborbital New Shepard space program, Blue Origin is working on an orbital-class rocket called New Glenn. There’s also a lunar lander called Blue Moon in the works.

Blue Origin’s New Shepard spacecraft and its hydrogen-fueled BE-3 rocket engine are built at the company’s headquarters in Kent.

New Glenn will use a more powerful engine known as the BE-4, which is fueled with liquefied natural gas. BE-4 engines are currently being manufactured in Kent and tested in Texas. However, engine production is expected to shift to Alabama, with the New Glenn rocket destined to be built and launched in Florida.

Blue Origin recently released a video highlighting the latest design of the New Glenn rocket, which has a wider payload fairing and a whiter paint job:
