CAPE CANAVERAL, Fla. (AP) — SpaceX stands ready to launch a much-needed load of supplies to the International Space Station this weekend on the heels of a failed supply run by Russia.

Besides food and experiments, the Dragon cargo ship ordered up by NASA holds a new docking port, or parking place, for future commercial crew capsules.

Liftoff is scheduled for 10:21 a.m. Sunday. Good flying weather is forecast for SpaceX’s unmanned Falcon rocket.

SpaceX capsule to deliver new parking spot for space station

CAPE CANAVERAL, Fla. (AP) — SpaceX stands ready to launch a much-needed load of supplies to the International Space Station this weekend on the heels of a failed supply run by Russia.

Besides food and experiments, the Dragon cargo ship ordered up by NASA holds a new docking port, or parking place, for future commercial crew capsules.

Liftoff is scheduled for 10:21 a.m. Sunday. Good flying weather is forecast for SpaceX’s unmanned Falcon rocket.

This shipment is especially critical because the space station has lost two deliveries since fall.

A Russian supply ship spun out of control shortly after liftoff in April and burned up on re-entry with all its contents. In October, an Orbital Sciences Corp. cargo carrier was destroyed in a Virginia launch explosion.

Once again, SpaceX is picking up the slack. This will be the eighth station supply run for the California-based company; the first was in 2012.

“Dragon has been super reliable,” SpaceX’s Hans Koenigsmann told reporters Friday.

Nearly 5,300 pounds of gear is packed for the trip, including replacements for science experiments lost in the Orbital launch accident, some of them designed by students.

Stored in the capsule’s unpressurized trunk is the first of two new docking rings for the station. Spacewalking astronauts will hook up the 1,160-pound port built by Boeing later this summer.

The twin ports eventually will be used by astronauts arriving in new American-built capsules. NASA is paying billions of dollars to SpaceX and Boeing to develop the crew capsules. The SpaceX version is a souped-up Dragon. Boeing’s model is the CST-100, short for Crew Space Transportation; the 100 represents the beginning of space at 62 miles up, or 100 kilometers.

In both cases, manned flights are still at least two years off. Until then, Americans will continue to hitch rides to the space station on Russian rockets for tens of millions of dollars per seat.

The Russian Space Agency plans to take another stab at a station shipment from Kazakhstan next Friday. Russian space officials want to see how that goes before launching a new three-man crew to the station on July 22, two months late because of the April cargo ship mishap.

Three men currently are living at the space station, three fewer than usual because of the recent hold in Russian Soyuz launches. Two of them are one-quarter of the way through a one-year mission: American Scott Kelly and Russian Mikhail Kornienko.

The third, Russia’s Gennady Padalka, will become the world’s most experienced spaceman this weekend. He’s set to break the world record for most accumulated time in space, surpassing the 803-day mark held by former cosmonaut Sergei Krikalev, now a Russian space program official.

By the time Padalka returns to Earth in September, he will have spent 2
