The core sentence after ignoring the inessential modifier is a compound sentence that is connected by the coordinate conjunction ‘and’. Apparently, it looks as if the second part is simply a prepositional phrase, but actually, the intended sentence has an element of ellipsis, that is implicit

Will be able to deliver a heavier load of instruments into orbit than the space shuttle can, and (will be able to deliver) at a lower cost.

It makes complete structural sense now and is parallel too logically. The ellipsis is not stated to avoid repetition In addition, the comparison between the two deliveries is matched with the use of the verb ‘can’

(E) A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle and to cost less.

The ellipsis doe not work well in E

will be able to deliver a heavier load of instruments into orbit than the space shuttle and (will be able to deliver) to cost less. One can see the ellipsis does not make much sense. Secondly, the verb ‘can’ is missing and thus it becomes an illegitimate comparison between the rocket’s delivery and the shuttle.

All this is my gut feeling; even without the ellipsis, still D can be decided simply by virtue of parallel comparison of actions and E will simply fall by the way side

IMO - D

in A,B,C,E - The development of a new jumbo rocket is compared with the space shuttle; whereas, the comparison should have been between A newly developed jumbo rocket and the space shuttle
Option left is D. Also, those options have other issues as well as highlighted below.

(A) The development of a new jumbo rocket that is expected to carry the United States into its next phase of space exploration will be able to deliver a heavier load of instruments into orbit than the space shuttle and at a lower cost.
>> parallelism issue with and

(B) The development of a new jumbo rocket is expected to carry the United States into its next phase of space exploration and be able to deliver a heavier load of instruments into orbit at a lower cost than the space shuttle.

(C) The new development of a jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit at a lower cost than the space shuttle.

(D) A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle can, and at a lower cost.

(E) A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle and to cost less.

Issue with comparison. In all choices except D "the development of J R" is compared with "S S".

A valid comparison can only be "the dev of J R" and "the dev of S S"
OR
"J R" and "S S".

D maintains this 'implicitly' by saying "than the space shuttle can" which translates to "than the [space shuttle's development] can" :)

Economist:
Your explanations really make sense thanks :)

(A) The development of a new jumbo rocket that is expected to carry the United States into its next phase of space exploration will be able to deliver a heavier load of instruments into orbit than the space shuttle and at a lower cost.

A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle can, and at a lower cost.

So you are saying the "CAN" makes all the difference??
Wow is this a rule of "can" or something?Links??

with regards to the comma, its listing of items and comma is optional

Compared to a space craft, newly developed jumbo rocket will be able to deliver a heavier load of instruments into orbit, and at a lower cost.

This GMAT question inspired this question: the-recent-discovery-of-a-red-oak-tree-sap-that-is-116992-20.html#p1627973

It has very similar problems.

The development of a new jumbo rocket that is expected to carry the United States into its next phase of space exploration will be able to deliver a heavier load of instruments into orbit than the space shuttle and at a lower cost.

(A) The development of a new jumbo rocket that is expected to carry the United States into its next phase of space exploration will be able to deliver a heavier load of instruments into orbit than the space shuttle and at a lower cost.
It's not the development of a new jumbo rocket that will carry the US into the next phace. This is illogical. It's the rocket itself!

(B) The development of a new jumbo rocket is expected to carry the United States into its next phase of space exploration and be able to deliver a heavier load of instruments into orbit at a lower cost than the space shuttle.
It's not the development of a new jumbo rocket that will carry the US into the next phace. This is illogical. It's the rocket itself!

(C) The new development of a jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit at a lower cost than the space shuttle.

(D) A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle can, and at a lower cost.
This is correct. The jumbo rocket is the noun being modified. The second split, "at a lower cost" sounds much better than E.

(E) A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle and to cost less.
While the first split is correct, the second sounds awkward because it is not parallel. To make it parallel, there would need to be a phrase after "to cost less" or "into orbit than the space shuttle" would need to be removed. Even then, the approach in E sounds better.

The challenge here is to revise the sentence and present a complex idea as simply as possible. What will deliver the instruments into orbit? They will be delivered not by the development of a rocket but rather by the rocket itself; the jumbo rocket, not its development, must be the subject of the sentence. The phrase a heavier load of instruments than the space shuttle suggests a comparison between the load of instruments and the shuttle, whereas it is actually the different capabilities of the rocket and the shuttle that are being compared. The comparison should be written: The jumbo rocket will be able to deliver a heavier load…than the space shuttle can. That is used to introduce restrictive clauses; such clauses are essential to the meaning of a sentence. The that is expected…exploration clause is not essential; it should be introduced by which and set off with commas.

(A) The subject should be the rocket, not its development; verb can is needed after space shuttle to create a correct comparison; that should be replaced by whichand the clause should be set off with commas
(B) The subject should be the rocket, not its development; verb can is needed after space shuttle to create a correct comparison
(C) The subject should be the rocket, not its development; verb can is needed after space shuttle to create a correct comparison
(D) Correct. The rocket is the subject of this sentence; the comparison between the rocket and the shuttle is clear; the nonrestrictive clause is correctly introduced and punctuated. Hence, D is the answer.
(E) Verb can is needed after space shuttle to create a correct comparison; to cost less is confusing because it seems to parallel to deliver
