The first part is true, but, "hurtling upwards through space" doesn't necessarily negate that the earth is "accelerating upwards through space." The only difference is that "accelerating" is more precise than "hurtling" because it has an added information to it. Therefore, either terms could have been used while (roughly) conveying the same concept.
